It's made from crushed limestone that's fired at very high temperatures, mixed with water, and colored with natural pigments. Though trendy, it's not new.
Limewash paint can be applied directly over breathable surfaces such as brick, cement, stucco and plaster. Previously painted surfaces should be primed first for best results.

Although many people love limewash paint, it does create a mottled look that is hard to control and may not be for everyone. Some projects may require several coats of paint to achieve the desired effect. In addition, the high pH means the paint can irritate skin and must be handled carefully.
The alkalinity deters wood-boring beetles and helps sterilise walls. Furthermore, limewash is inexpensive and solvent-free.

It can be hard to get the limewash to blend with water if you're mixing by hand. It costs more than paint. It isn't as long-lasting as whitewash – while it won't flake like paint, it still needs touch-ups regularly, and usually has to be redone every 5-7 years.
